I'm trying to add a corner and remove a wall from that corner on words, what the intention of partially removing a wall in the kitchen area. It's not working and when I render in 3D everything seems to be wonky, I see wall openings that are sometimes transparent from one side and filled in when looking through the other side. I then tried to insert openings in the wall to achieve the same result and the opening renders as a floating wall opening frame outside of the room completely distant from the wall where it's applied..
